A new Tangere survey conducted from March 16 to 18, 2026, shows Rodante Marcoleta clearly ahead of Risa Hontiveros by a 7-point margin if Vice President Sara Duterte is removed from the race.
The poll used a sample size of 1,500 respondents and reported a margin of error of ±2.77 percent at a 95 percent confidence level. It measured voter preference in the event that Duterte is impeached and unable to participate, showing how support may shift under that condition.
In the matchup, Marcoleta secured 28 percent, ahead of Hontiveros at 21 percent, establishing a 7-point lead among decided voters. The margin suggests Marcoleta draws broader support from voters who remain committed to a candidate in Duterte’s absence, reinforcing his position as the frontrunner. The gap indicates that even modest shifts among undecided voters could further strengthen his lead.
Jonvic Remulla registered 4 percent, while 47 percent of respondents remained undecided, indicating that nearly half of voters have yet to settle on a candidate under this condition.
Separate testing under a different configuration shows Bong Go and Leni Robredo statistically tied, with Robredo at 36 percent and Go at 35 percent. The 1-point gap falls within the survey’s ±2.77 percent margin of error, showing both candidates remain strong in overall voter preference.
In another configuration, Robredo leads Marcoleta with 40 percent to his 27 percent, while 33 percent of respondents remain undecided. The result indicates stronger consolidation of support around Robredo in a direct matchup, while Marcoleta retains a defined base.
Tangere stated that no data has yet been generated for Davao City Mayor Sebastian Duterte should he enter the race as a substitute for his sister, Vice President Sara Duterte, leaving a key variable in voter preference unaccounted for under this condition.
The findings capture voter sentiment during the survey period under the conditions tested and are not indicative of final election outcomes.
